Rotenone, a pesticide and inducer of PD symptoms, and amyloid-beta peptide, which is causally linked to Alzheimer's disease, initiate mitochondrial fission.
In addition, recent findings report increased mitochondrial fission in Parkinson's disease (PD) models and induction of mitochondrial fission by two proteins, PTEN-induced kinase 1 and parkin, which are mutant in familial forms of PD.

Loss-of-function mutations in PTEN-induced kinase 1 (PINK1) or parkin have been linked to early-onset autosomal recessive forms of familial PD.
Consistent with our previous findings from parkin knockout mice, rat models of PD (6-hydroxydopamine-, rotenone-, or MG132-induced PD) were also associated with an increase in soluble and insoluble PINK1 levels as well as enhanced formation of parkin aggregates.

PLoS One. 2009 May 27;4(5):e5701.

PTEN-induced novel kinase 1 (PINK1) mutations are associated with autosomal recessive parkinsonism.
We also show that wild-type PINK1, but not recessive mutant or kinase dead versions, protects against rotenone-induced mitochondrial fragmentation whereas PINK1 deficient cells show lower mitochondrial connectivity.

PTEN-induced kinase 1 (PINK1) is a recently identified gene, mutations of which cause levodopa-responsive parkinsonism.
Incubation with PINK1 siRNA decreased SH-SY5Y cell viability and significantly increased MPP (+) or rotenone-induced cytotoxicity.

Treatment with rotenone or antimycin A also resulted in increased wortmannin-sensitive Akt phosphorylation, probably by increasing intracellular H2O2 generation by blocking mitochondrial electron transport.
